IVE-BOILER.

SPECIFICATION forming part of Letters Patent No.f692,896, dated February 11, 1902.

Application filed June 51 1901 To all whom it may concern:

Be it known that LCHARLES WESLEY N EW- TON ,a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in L0- comotive-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to locomotive-boilers in which the usual horizontal fire-tubes are dispensed with and in which a series of manifolds are placed in an inner shell and also in the fire-box, by which construction a more rapid and better generator is produced, the

heat being brought more in direct contact with the water where the heat is greatest and which when the boiler is in use is kept in con stant circulation and by which circulation the heat is more readily taken up, a better separation of the steam from the water is maintained, and a better distribution of the heat to all parts of the boiler is provided for,

equally distributing the temperature and equalizing the strain to all the parts.

Referring to the drawings, Figure l is a vertical longitudinal section through a locomotive boiler, showing my improvement. Fig. 2 is a vertical cross-section through the fire-box, and Fig. 3 is a similar section through the forward part of the boiler.

A is the usual outer shell of a locomotive-boiler, to which is connected the steamdome G.

B is a part of inner shell with the waterlegs land the usual fire-box H. O is the semicylindrical flue leading from the fire-box H through the cylindrical part of the outer shell A to the smoke-box E, the outer end of which is secured to the'head D and also the outer shell A.

. serial No. 63,251. (No model.)

The manifolds Fin the fire box are different from those in the flue.

Manifolds F consist of a series of vertical water-tubes connected to a horizontal header K' at the top, to an arched header L at the bottom, and all cast in one piece. The vertical water-tubes extend to a short distance above the upper head at A and by tubes 0 are secured to the flat crown-sheet M of that part of the inner shell B which forms the firebox, by which the crown-sheetis braced and communication established.

The ends of each header are open and in which are secured short tubes N, by which the manifolds F are secured to the sides ofthe furnace or tire-box, and having supply-openings for the water to circulate through the manifolds and also serve to brace the tire-box.

As is usual in locomotive-boilers,the crownsheet is braced by the T-bars O, secured to the same by rivets passing through the forrule-tubes E, and bars D fastened to the said plate 0, and the T-irons P P, which are secured to'the outer shell.

Since the fine is fiat on its upper side, like that of the fire-box, and the upper part of the manifolds F arethe same as manifolds F, the foregoing description of the manifold F in the manner it is secured to the inner shell and provision for circulation of the Water applies also to the manifolds F, excepting the lower header Q. This lower header Q of manifolds F shows a segment of a circular conforming to the curve of the lower part of the fine. The lower part of the manifold F is provided with a connection 9, which, like the other tubes N and C, connects the manifolds to the flue and provides another inlet for the circulation of the water and also for the drainage from the manifolds when the boiler is emptied or blown off.

From the foregoing description it will be seen that by my arrangement of manifolds in the fire-box and in the cylindrical portion of the boiler a largely-increased area of effective heating-surface is obtained over that of the same length and class of boiler of the ordinary or tubular type. It will be readily seen that the rapid circulation-of the water through these manifolds keeps the surface clean -from sedimentary deposits, and there- ICO fore avoids incrustation when the water is impure.

Having described my improvement in the best manner known to me at present, I do not Wish to be understood as limiting myself to the exact construction herein set forth nor to the details described therein, but claim such modifications as may seem desirable without parting from the spirit and scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a locomotive-boiler the combination of the fire-box with a series of manifolds secured to the crown-sheet and the sides of the fire-box and means for circulating the Water through the manifolds.

2. In a locomotive-boiler the combiuation of the fire-box with a series of manifolds consisting of an upper and lower header, tubes connecting said headers, tubes projecting from the upper header and secured in the crown-sheet and tubes in the ends of headers for securing the manifolds to the sides of the fire-box.

3. In a locomotive-boiler the combination of the fire-box with a series of manifolds, consisting of an upper horizontal header, alower arched header, vertical water-tubes connecting said headers, tubes projecting from the upper header and secured in the crown-sheet and tubes in the ends of the header for securing the manifolds to the sides of the fire-box whereby circulation is provided for and es: tablished. 1

4. In alocomotive-boiler the combination of the outer shell, and fine, the latter having a fiat top with manifolds consisting of anupper horizontal header, a lower header conforming to the curve of the flue, tubes in the ends of both headers, and the lower point of the bottom header connecting the manifold to the curved portion of the flue, and tubes projecting from the upper header and secured in the flat portion of the fine.

5. In a locomotive-boiler, the combination of the outer shell and inner shell or flue, the latter having a flat top with manifolds consisting of an upper horizontal header, alower header conforming to the curve of the flue,

tubes connecting said headers and tubes in the ends of both headers, and lower point of bottom header connecting the manifold F, to the curved portion of the fine, tubes projecting from the upper header and secured to the crown-sheet, and means for bracing the crownsheet to and by the manifold substantially as described.

6. The combination in a boiler of the locomotive type of a cylindrical portion and sectional portion, the sectional portion being secured to and within the cylindrical portion by hollow brace connections, and the fire-box portion having dependingsections secured to the crown-sheetalso by hollow connections, thesection in the cylindrical portion being adapted to circulate water through the top, bottom and side thereof, and the section in the fire-box being adapted to circulate water through the crown-sheet and the water-legs, thus forming means for a thorough, entire and constant circulation of the water in the boiler through all its parts, simultaneously, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES WESLEY NEWTON.
